A further object of my invention is "to provide a clothes-wringer, which may have a frame made wholly of metal, with quick acting release mechanism for the pressureapplying means for the squeeze-rolls.

And a still further object of my inven tion is to-provide'ajniimproved form of pressure-ap lying means for use with thebearings, w 1ch may be of wood,'. employed with the-spindles of the squeeze-rolls; the upper bearings, which overlie the spindle of the upper squeeze-roll, being provided with a simple form of wear-member to take the thrust and wear occasioned b the pressure-applying means which are irectly associated with the quickrelease device.

These and other features of my inven tion, are more fully described hereinafter, reference bein drawings, in w ich:

The improved wringer frame to which the features constituting my present invention have. been applied may be of metal, substantially- U-shaped, in contour, and may f comprise upright hollow end portions with a lower connecting cross-bar; such frame being formed in one or a plurality of sec:

tions. In the drawing I have illustrated a frame made of a plurality of sections, 1 and 2 fitting together on a median or substantlally median line, as clearly illustrated in Fig. 2, 'andsecured in place by suitable means; such for instance, as the rivets 3. Such frame ma be identical with, that shown" and descrlbed inmy pending application, filed Sept. 24, 1920, Ser. No. 412,449.

The sections 1 and 2 areprovided with upright end portions 1 and 1", and 2* and 2", and these end portions may be provided with inwardly disposed flanges or ribs 4, providingchannels adapted to receive hearing blocks 5, for the spindles 6, or squeeze" ro ls 7 5 said bearing blocks'having side ribs 5 fitting the channels provided by the flanges 4. These bearingsare preferably of hard wood, and may be cut from a previously formed blank in the manner described in my application before referred to. The bearing blocks. are applied to the upper side of thespindle of the upper roll and the lower side of the spindle of the lower'roll, and'the lower bearings may be supported by inwardly disposed lateral projections 8 carried ,by ardsof theframe.

eachfupright end portion lit-and 2" oi the mounted in pairs of cars 13 and let of the cap members 13 and 14; said bolts being adapted to underlie pairs of lugs 16, carried by the upright end portions 2 and 2 of the section 2. The bolts 15 carry springs 17 interposed between washers 18 and 18 also carried by the bolts and which may be cupped to receive the ends of the springs; the washers 18 directly underlying the respective pairs of lugs 16. The bolts may 15 be provided with suitable nuts 19 engaging the washers 18 whereby the tension of the springs 17 may be adjusted to an extent to hold the parts securely in position and apply the desired pressure to the squeeze- 20 rolls. The cap 14 is provided with -an extension 14' preferably integral therewith, to overlie the gear housing 9.

In the present instance, the wringcr structure is provided with an improved form of ressure-applying device for the squeezero s 7, comprising lugs or projections 20 and 21 disposed on the under sides of the ca members 13 and 14 respectively, and pre erablyintegral therewith, which lugs or projections directly engage wear pieces. 22,

'in the form of metal yokes, carried by the bearing blocks 5, for the spindle of the up.- per squeeze roll; the leg portions of which yoke members lie in grooves 5 formed in the side portions of said bearing blocks,

. and nominally engage the side walls of the upright end portions.

In this arrangement of my improved quick-release mechanism, the bolts 15 have upwardly extending members or projections 23 disposed at an angle with respect to said bolts so as to extend over the squeeze rolls, and the upper ends of said members 23, are connected at 24, to a cross-bar 25, which forms anoperating handle. The members 23 may be integral with the bolts 15 or rigidly secured thereto. By depressing said handle'25, the bolts 15 may be swung on their pivot pins 15, and release the springs 17 from engagement with the pairs of the lugs 16. To completely release this pressure-applying device it is only necessary to depress the handle25 tothe position shown by dotted lines in Fig. 2, whereupon the 5 spring bolts 15 and the caps 13 and 14 will be withdrawn from their operative engagement with the lugs 16 and all danger of the fingers of the operator being injured if caught between the squeeze rolls is avoided; the upper roll being completely freed, fromthe pressure applied by the spring 17. In.

like manner, the rolls may be released if the garments paming through the squeezerolls tend to catch upon the same and wind thereon.

. In the structure illustrated in Figs. 4, 5, et seq., the frame of the wringer is of the same type as that illustrated in Figs. 1 and 2, and the same form of cap members 13 and 14, having the lugs 'or projections 20 and 21 respectively, on their under side, for engagement with the yoke members carried by the bearing blocks for the spindle of the upper squeeze-roll, are employed. Instead of mounting these bolts on independent pivot pins, however, I provide a cross-bar 30, journaled'in the pairs of ears 13 and 14: of said cap'members; said cross-bar being squared or otherwise shaped at 31 to have a position connection with said bolts 15, so that any rotative movement applied to said cross-bar will tend to move the bolts from their engagement with the pairs of lugs 16 of the end portion 2 and 2", of the sections 2.

L For the purpose of actuating the crossbar 30, it may be provided with a. laterally disposed arm or handle 33, which may be dis osed at a right angle to the cross-bar, an extend above the same. It will be understood, therefore, that when this handle 33 is depressed to a suflicient extent, that indicated by dotted lines in Fig. 6, for instance, it will disengage the bolts 15 from the pairs of lugs 16, thereby releasing the springs 17 applying pressureto the rolls and avoiding all danger of the fingers 'of the operator becoming pinched between the I same. In like manner, the rolls may be released if the garments passing through the squeeze rolls tend to catch upon the same and wind thereon.

As in the structure of my ending application before referred to, a rain board 35, also of metal may be arranged to lie below housings 36, formed on the inside of the upright end portions of the frame for the outer ends of the squeeze-rolls in each form of structure, and this drain board may be vadjustably held in place in the same-manner as illustrated in my pending application.

The usual guide plates 37, to direct the garments to the bite of the squeeze-rolls may be employed, as in all similar structures, said guide plates having projections 38 which engage the edges of the housin s 36.

ower to'drive the squeeze rolls may be applied to either spindle but in the present case I have shown the lower spindle as projecting beyond the end of the frame as indicated at 6, for operative engagement with a driving element; the shaft of a suitably actuated motor for instance. In lieu of this, the projecting spindle may be en-' gaged by a suitable crank handle, or other form of power-applying member.

As in the structure of my pending application, it will be readily understood that as soon as the cap members 13 and 14 are released from engagement with the wear memready assembly and removal of the various parts of the structure, "for renewing the hearings or squeeze-rolls or other repairs, as occasion may. require, 7 There are noparts to get out of order or're'adily'break, and any suitable form of clamping device may be employed to attach my improved wringer to a washing machine, or tub, or at any other desiredpoint.

It will be understood that I do not wish to be limited to the exact construction disclosed in the drawings and described herein, and my claims are designed to cover any equivalent construction having the same or a similar object in view. It will also be understood that my improvements may be applied to wooden or metal frames, and

that the latter may be made of cast or ressed metal, without departing from m invention.
